Smoking... fetish?

I just spent 15 minutes Googling "Katherine Heigl smoking."

Okay, so I have a smoking fetish. For those of you who don't know what this is, it's the situation where a woman (in my case) who smokes is a turn-on. If a pretty woman is smoking, she becomes even more sexy to me. I know, it's a bit deviant. Not much I can do about it. I remember in high school watching this pretty red-head named Greta, standing in the corner of the school lot where all the smokers gathered. She would purse her pretty pink lips and inhale from her cigarette. I'd watch it glow for a minute, then she would pull it of her mouth and exhale this thick, long stream of smoke. And that turned me on. I know it's not mainstream really, but then again, it's not completely crazy. It's not like chicks eating poop, or even quite as strange as a foot fetish, right? I mean, at least it's oral-related. My girlfriend is an ex-smoker, and I know she's tempted to smoke occasionally. I refrain from tempting her because, despite the fact that I would love to see her smoke again, I know it's unhealthy and I want the best for her. But damn, it's so sexy! Weirdly enough, I don't smoke. I actually don't even like the smell of cigarettes, and on the few times I've tried smoking, it makes me feel kind of sick. It's more of a visual turn-on for me, although kissing and fooling around with a girl while she's smoking is positively erotic.

I can't help but wonder how one becomes a smoker. I mean, it doesn't taste good when you first do it. And it takes SO much practice to get your lungs used to it, and quite a long time before you get addicted. How do we have so many smokers in the world? I mean, sure, you can say "I smoke when I drink", but I'm sure many people become smokers without ever drinking. It just blows my mind that something so difficult to do and takes so long to get addicted, is actually so popular and has so many people addicted to it.

I suspect that if you can explain one type of fetish, you can probably explain them all. Surely it's all related to something that happened in your youth or some crap like that. I mean, why would a guy like to see... bare feet? I mean, it's harmless enough, but difficult for me to understand. (As I'm sure my smoking fetish is difficult for some people to understand.) If you search on YouTube for smoking fetish, you'll find zillions of videos of chicks smoking. I don't claim to understand it. It just "is", I guess. Any psychologists reading this have any idea why I find this so attractive?
